Now THIS took some creativity. If you’ve got a decent internet connection and have ever used Google Maps, you can appreciate just how cool this is: A cartoon-city experienced via the GoogleMaps API. There’s lots and lots (and LOTS!) of things to see. A few things that caught my eye:

A Graboid.
Daleks (but no TARDIS!?)
Dr. Manhattan.
Link.
Monsters from the original DOOM video game (and not just the ones in the Doom II zone)
The Aperture Science facility
Spider Jerusalem vs. The Joker(s)
Lots of Batman/Joker references
ZOMBIES!!
Invader Zim
Back to the Future
Leeroy Jenkins
A pretty big military base
Jay and Silent Bob
The A Team.
…just to name a few!
